Description

Technical Field

[0001] The utility model relates to the technical field of waste gas recovery, in particular to a splash-proof liquid collection tank device. Background Art

[0002] In the recovery and treatment of organic waste gas, water and NMP waste gas are in countercurrent contact in the device. The gas enters the distributor from the riser pipe, and the liquid enters the liquid guide pipe through the spray holes and is distributed to the packing through the liquid distributor in the liquid guide pipe. As Figure 1 shown, in the existing technology, a concave liquid baffle is arranged below the spray holes. When spraying, water will splash into the riser pipe between the riser pipe and the baffle, resulting in the imbalance of gas-liquid distribution, the rise of the bottom liquid level, the reduction of the working efficiency and effect of the liquid collection tank, and even flooding of the tower.

[0003] Therefore, this solution proposes a splash-proof liquid collection tank device. By installing a chevron liquid baffle, the splashing liquid can be more effectively blocked and made to flow along a predetermined path. Summary of the Utility Model

[0004] The utility model aims to at least solve the problems such as flooding of the tower caused by the excessive liquid level in the liquid collection tank due to the liquid splashing into the riser pipe during spraying in the existing technology.

[0005] This solution provides a splash-proof liquid collection tank device, which is achieved by the following specific technical means: including a tower body liquid collection tank, a concave liquid baffle is arranged on the liquid guide pipe in the tower body liquid collection tank, and a chevron liquid baffle is arranged between two adjacent groups of concave liquid baffles. The height of the chevron liquid baffle is higher than that of the concave liquid baffle, so that the liquid sprayed from the spray holes and falling outside the concave liquid baffle, that is, the liquid above the riser pipe, is blocked by the chevron liquid baffle.

[0006] Preferred Technical Solution 1: The chevron liquid baffle is located above the air outlet of the riser pipe, and the two low ends on both sides respectively extend to directly above two adjacent groups of concave liquid baffles. The liquid blocked by the chevron liquid baffle falls back onto the concave liquid baffle, and the gas entering the tower body liquid collection tank from the riser pipe is discharged laterally from the bottom of the chevron liquid baffle.

[0007] Preferred Technical Solution 3: The chevron liquid baffle is an inverted V-shaped plate with an included angle of 120 degrees.

[0008] Adopting the above structure enables this solution to have the following beneficial effects:

[0009] On the existing liquid collection tank, the chevron liquid baffle is installed at a high position between two adjacent groups of original concave liquid baffles, effectively blocking the splashing liquid, making it flow in different directions, improving the uniformity of liquid distribution, and enhancing the gas-liquid contact efficiency.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 2 - 3 , the anti-splash liquid collection tank device includes a liquid collection tank 1 of the tower body. A concave liquid baffle 2 is arranged on the liquid guide pipe in the liquid collection tank 1 of the tower body. At the same time, the spray hole 5 arranged in the liquid collection tank 1 of the tower body is located above the concave liquid baffle 2. Due to the action of gravity, the liquid tends to flow downward, while the gas moves upward. The concave liquid baffle 2 in the prior art initially blocks and guides the flow of the liquid, enabling it to achieve preliminary distribution and deceleration to a certain extent. In the present solution, a herringbone liquid baffle 3 is arranged between two adjacent groups of concave liquid baffles 2. The height of the herringbone liquid baffle 3 is higher than that of the concave liquid baffle 2, so that the liquid sprayed from the spray hole 5 and falling outside the concave liquid baffle 2, that is, the liquid falling above the riser pipe, is blocked by the herringbone liquid baffle 3. The liquid contacts the herringbone liquid baffle 3. The red arrow represents the liquid flow direction. The herringbone liquid baffle 3 further divides and deflects the liquid, enabling the liquid to disperse and flow in different directions along the surface of the herringbone liquid baffle 3. In this process, the herringbone liquid baffle 3 changes the flow speed and direction of the liquid, enabling the liquid to be more evenly distributed in each part of the trough plate in the liquid collection tank 1 of the tower body.

[0017] Please refer to Figure 3, splash-proof liquid collection tank device. On both sides below the chevron-shaped liquid baffle 3, vertical frames 4 are fixed to the sides of adjacent two groups of concave liquid baffle 2. The chevron-shaped liquid baffle 3 is installed on the top of the vertical frame 4. The chevron-shaped liquid baffle 3 is located above the riser pipe and the two low ends on both sides respectively extend to directly above adjacent two groups of concave liquid baffle 2, so that the liquid blocked by the chevron-shaped liquid baffle 3 falls back onto the concave liquid baffle 2. The gas entering the tower body liquid collection tank 1 from the riser pipe is discharged from the vertical frame 4. The blue arrow represents the gas flow direction. During the upward movement of the gas, it will be hindered and guided to a certain extent by the chevron-shaped liquid baffle 3, adjusting the gas flow rate and direction. The upper layer of liquid will not splash to the lower layer, promoting the full contact and mixing of the gas with the more evenly distributed liquid.

[0018] Please refer to Figure 3 , splash-proof liquid collection tank device. The concave liquid baffle 2 is a V-shaped plate with an included angle of 120 degrees. The chevron-shaped liquid baffle 3 is an inverted V-shaped plate with the same included angle of 120 degrees.

[0019] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
